“After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me.
Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny.
So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue.
Also, it is worth pointing out that it’s not like we’re “done” with spectre/meltdown. There is more work pending (arm, spectre-v1, misc details), and perhaps equally importantly, to actually get the biggest fix for the indirect branch mitigations, you need not just the kernel updates, you need to have a compiler with support for the “retpoline” indirect branch model.”
